If you signed up for the Canadian Dental Care Plan in 2024 or 2025, your coverage does not roll over automatically. Every member has to renew once a year, and the window for the 2026-2027 benefit year opened on April 15, 2026. You have until June 1, 2026 to get it done. Miss that date and your coverage ends on June 30, with no retroactive reimbursement for any dental work done during the gap.

The good news is that renewal is much shorter than the original application. For most people it takes about ten minutes. This guide walks you through what to have ready and exactly where to click or call.

Before You Start: File Your Taxes

This is the one step that trips people up. Service Canada uses your most recent tax return to confirm you still qualify for the CDCP. Your 2025 income tax return must already be filed and assessed by the Canada Revenue Agency before the renewal can go through.

If you haven’t filed yet, do that first. You can file for free through community tax clinics if your income is modest. The CRA keeps an updated list at Free tax clinics through the Community Volunteer Income Tax Program. Once your Notice of Assessment arrives, you’re ready to renew.

You will also want these items in front of you:

  • Your Social Insurance Number (SIN)
  • Your CDCP member ID (on the welcome letter Sun Life mailed you)
  • Your current mailing address, phone number, and email
  • Confirmation that you still don’t have access to private dental insurance through work, a pension, or a spouse

Option 1: Renew Online (Fastest)

If you’re comfortable using a computer or tablet, this is the quickest route.

  1. Go to Renew your Canadian Dental Care Plan coverage on Canada.ca.
  2. Sign in to your My Service Canada Account (MSCA). If you’ve never used MSCA before, you can register with a GCKey or through your online banking sign-in partner.
  3. Find the Canadian Dental Care Plan section on your dashboard.
  4. Select Renew my coverage and follow the prompts. You’ll confirm your address, your insurance status, and that you agree to the plan terms.
  5. Submit. You should see a confirmation screen, and Sun Life will mail or email you a new welcome package once you’re approved.

A note for anyone helping a parent or older relative: MSCA logins are personal. You can sit beside them and walk them through it, but the account has to be in their name with their SIN.

Option 2: Renew by Phone

Plenty of CDCP members would rather speak to a person than fight with a website, and Service Canada has set up a dedicated line for that.

  • Service Canada CDCP line: 1-833-537-4342
  • TTY (for the hearing impaired): 1-833-677-6262
  • Hours: Monday to Friday, 8:00 a.m. to 8:00 p.m. local time

Wait times tend to be shortest first thing in the morning and worst around lunch. When you call, the agent will ask for your SIN, your date of birth, and a few questions to confirm your identity, then they’ll walk you through the same renewal questions you’d see online.

If you’re stuck on hold, hang in there. Renewal calls run shorter than new applications.

Option 3: Visit a Service Canada Centre

For anyone who’d rather do it in person, you can walk into any Service Canada Centre and an agent will help you renew on the spot. Bring your SIN card, photo ID, your CDCP welcome letter, and proof of address. Toronto has several centres downtown. The closest one to our Bay Street office is at College Park.

What Happens After You Renew

Once Service Canada approves your renewal, Sun Life updates your coverage for the 2026-2027 benefit year, which runs from July 1, 2026 to June 30, 2027. Your member ID stays the same, so you don’t need a new card for your dentist. The system reads that you’re still eligible.

If your income changed in 2025, your co-payment level may shift. Households under $70,000 pay nothing out of pocket for covered services. Households between $70,001 and $79,999 pay 40% of the CDCP fee, and those between $80,000 and $89,999 pay 60%. Sun Life will spell out your exact share in the new package.

Don’t Wait Until the Last Week

Service Canada’s call centre and the MSCA portal both get backed up in the final days of May. Two practical tips:

  • Renew in late April or early May, not the week of June 1.
  • If you have a cleaning, exam, or any procedure scheduled in June or early July, renew first. A claim submitted between June 30 and the day your renewal is approved won’t be reimbursed retroactively.

Booking Your Next Appointment

We see a lot of CDCP patients at our Bay Street office, and many of them are coming in for the first cleaning they’ve had in years. If you’ve just renewed and want to get your covered services in before the next renewal cycle, give us a call at (647) 483-6906 or book an appointment online. Our team speaks Cantonese, Mandarin, Tagalog, and English, and we’re happy to walk you through the billing side so there are no surprises.

Renewal is a small administrative task that protects a year of dental care. Ten minutes now saves a real headache in July.
